Check Digit Verification of cas no

The CAS Registry Mumber 1616603-31-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,6,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1616603-31:
(9*1)+(8*6)+(7*1)+(6*6)+(5*6)+(4*0)+(3*3)+(2*3)+(1*1)=146
146 % 10 = 6
So 1616603-31-6 is a valid CAS Registry Number.

Copper-catalyzed 5-endo-trig cyclization of ketoxime carboxylates: A facile synthesis of 2-arylpyrroles

Du, Wei,Zhao, Mi-Na,Ren, Zhi-Hui,Wang, Yao-Yu,Guan, Zheng-Hui

, p. 7437 - 7439 (2014/07/07)

A novel and facile copper-catalyzed 5-endo-trig cyclization of ketoxime carboxylates for the synthesis of 2-arylpyrroles has been developed. The reaction tolerates a range of functional groups and is a practical procedure for rapid synthesis of 2-arylpyrroles in high yields under mild conditions. the Partner Organisations 2014.
